Juniperus navicularis - a study of Portuguese population structure and fitness

Juniperus navicularis Gand. is a dioecious endemic conifer that constitutes the understory of seaside pine forests in Portugal, areas currently threatened by increasing urban expansion. The aim of this study is to assess the conservation status of previously known populations of this species located on its core area of distribution. The study was performed in south-west coast of Portugal. Three populations varying in size and pine density were analyzed. Number of individuals, population density, spatial distribution and individual characteristics of junipers were estimated. Female cone, seed characteristics and seed viability were also evaluated. Results suggest that J. navicularis populations are vulnerable because seminal recruitment is scarce, what may lead to a reduction of genetic variability due solely to vegetative propagation. This vulnerability seems to be strongly determined by climatic constraints toward increasing aridity. Ratio between male and female shrubs did not differ from 1:1 in any population. Deviations from 1:1 between mature and non-mature plants were found in all populations, denoting population ageing. Very low seed viability was observed. A major part of described Juniperus navicularis populations have disappeared through direct habitat loss to urban development, loss of fitness in drier and warmer locations and low seed viability. This study is the first to address J. navicularis conservation, and represents a valuable first step toward this species preservation. 

Society, theatre and Social Work: beauty will save us

Three different worlds, sometimes concentric and often intersecting —society, theatre and the art of performance— and social work. Diverse worlds that live, reflect and self-reflect and interact, and can also afford an opportunity for meeting, misunderstanding and confrontation, and above all offer the possibility of profound change.This article considers the experience of a theatre company that has spent more than three years moving at the limits of these three universes. To these three worlds can be added an infinite number of words that fill them with meaning and significance: territory, meeting, diversity and search. An artistic experience that has chosen to focus on creating scenarios for debate and to examine the difficulties, the human contradictions and the constant and inexhaustible confrontation with human experience. At the heart of this theatrical activity is all of this, seeking the balance between narration, meeting, investigation and the artistic dimension. This meeting between society, theatre and social work also contains the search for sustainability of this cultural business, in an Italy that has been destroyed by a crisis that is not merely economic, but also of values and, above all, of role models. The guiding theme, though not always made explicit, is always present and essential: the search for beauty.

How teachers of Geography and History of Secondary Education assess?

The purpose of this article is to analyse the assessment procedures and instruments used by teachers of Geography and History of Compulsory Secondary School (ESO) in the Region of Murcia (Spain). The data have been extracted implementing a survey technique proceeded by a descriptive analysis. The results show that teachers generally have a traditional conception of assessment, reflected in the fact that they think that assessment should not change when teaching strategies are changed or when they innovate. On the other hand, although they consider that is necessary to employ a variety of instruments to assess well and to prevent school failure, they still use exams as the most objective and essential instrument in the assessment, while they don’t apply continuous assessment, only tests in a continuous way. The implementation of similar research in other areas or in other subjects shows the existence of contrasts in teacher assessment practices.

El Instituto antes de Salamanca. Los primeros años del Instituto de Investigaciones y Experiencias Cinematográficas (1947-1955)

El presente texto analiza la función del Instituto de Investigaciones y Experiencias Cinematográficas (IIEC) como punto de encuentro de la cultura cinematográfica nacional entre 1947 y 1955 —los años de Victoriano López— y dirige el foco analítico a los discursos, debates e intereses que marcaron la labor del instituto en estos primeros años. Para ello, este artículo fija su atención en uno de los pocos docu­mentos originales conservados de esa época, un boletín publicado por los alumnos en 1951, material que será aquí completado con entrevistas y los escasos documentos referentes al instituto conservados en el Archivo General de la Administración. La piedra de toque del análisis la constituyen por un lado las ac­tividades del cineclub, organizado por los alumnos de la clase de Historia del Cine en 1951, y, en el plano discursivo, los debates en torno a la Filmología, doctrina con la que desde 1947 se intenta dotar a las acti­vidades del Instituto de una base teórica con desiguales resultados. Se consigue así un acercamiento a las prácticas y discursos esenciales para comprender la importancia del instituto como punto central dentro de una naciente cultura cinematográfica nacional.
